Is this supposed to be a trick question?
20 pounds of feathers be the same weight as 20 pounds of sand?
They're both 20 pounds.
They total the same, a handful of sand for example would weigh more than a handful of feathers but because they both add up to a specific weight neither is heavier than the other there would just be more feathers than sand..
because sand is smaller than feathers and it would take up as much space with the sand , and if the feathers were there it would take up more space because its and larger object than the sand .
Because sand is a more dense substance than feathers - it has a larger mass-to-volume ratio.
a cup is considered a liquid measurement, not weight. eg: what is heavier, a cup of feathers or a cup of sand?
A kilogram of sand takes up much less space than a kilogram of feathers because sand is denser than feathers. Density refers to how much mass is contained in a given volume. Since sand particles are heavier and more compact than feathers, they occupy less space for the same mass.
No, sand is freaking heavy
